Radiation is basically energy moving from one place to another, in either waves or particles. There are two types of radiation: ionizing and non-ionizing. Ionizing radiation comes from radioactive sources or nuclear reactions and is the type that causes mutations and malignant cancers. Non-ionizing radiation is what cell phones emit and contains less energy than ionizing radiation, therefore making it less harmful. But it IS still harmful. Non-ionizing radiation can enter the body and harm sensitive tissue.

The Weizmann study found that using certain cell phone for even 15 minutes was capable of triggering cellular brain changes commonly linked to cancerous cell division.

The Associate Director of the National Institutes of Health, National Toxicology Program, Dr. John Bucher, said, “As of now, with only 10-12 years exposure, and use increasing dramatically, there is a concern of increase in brain cancer, related to use.”

He added that children in early developmental stages are at greater risk due to their skulls allowing deeper penetration of radiation.

1. Use a headset
2. Use the speakerphone option
3. Text more, talk less
4. Purchase a low radiation phone (see list below)
5. Stay off the phone when you have a weak signal. Weaker signals mean more emissions to contact the tower.

The EWG also released a list of the top 5 cell phones with the lowest emitted radiation. The results show the maximum possible SAR level from the phone. SAR, or Specific Absorption Rate, measures the rate which the body tissue absorbs radiation energy while using cell phones.
